Yep. I was gonna say, sounds like a water hammer issue. Happens when the valve closes too quickly, all the momentum of the water moving through the pipes has nowhere to go, so it slams the pipes around. Should be a relatively easy fix (if you have any plumbing skills), a special damper that goes in the pipeline to absorb the excess energy.

dr. turducken,

i read this on the interwebs so it must be true:

"Plumbing that's properly installed has air chambers, or cushions, that compress when the shock wave hits, softening the blow and preventing this hammering. The chambers can fail, though, because water under pressure gradually absorbs the air.

"If you never had hammering and then it suddenly starts, most likely your plumbing system's air chambers have become waterlogged. You can cure water hammer by turning off the water behind the waterlogged chamber, opening the offending faucet and permitting the faucet to drain thoroughly. Once all the water drains from the chamber, air will fill it again and restore the cushion. If the air chamber is located below the outlet, you may have to drain the main supply lines to allow the chamber to fill with air again."

(the air chamber being deadended vertical runs of pipe near each valve or faucet. that is, mabe all they have to do is drain the plumbing then refill, w/o installing any new dampers.)

yep. sounds about right. I had the water heater expansion tank pictured in my mind (which will also help muffle the hammering), but reading that description points out that there probably are anti-hammer standoffs already installed in the line that just need cleaning/draining since the problem started rather suddenly.

Conductive thread is thread that conducts electricity. I am making a hoodie that has our department logo on the back (done) with 12 LEDs sewn in a matrix (done) that will connect to a LilyPad Arduino controller board on the front of the jacket and hopefully a sound sensor, although the more I look at it I think the voltage may be too high on the one I ordered from Amazon which has the 5 day 2 day shipping for some reason.... I'd order one that I'm fairly sure will work, but it's going to take too long to get here. The program I have written for the lights will work without the sensor, the sensor is just to make it more interesting. (and yes I am making it for work, sorta)

I have no clue what you are talking about.

WE LURV YOU TOO! Dork!!!
No greater love is lost than that not shared.

Hi all. Dad update. He had a wonderful day today. Actually went out with me to my chiropractic/massage appt. Stayed in the car. Then we ate lunch at a buffet. Its the first time he has been out of the house since the 30th of March.

His step son called yesterday and they had a good chat. Nice he seems to have quit playing games and making me the bad guy.

Tomorrow a good friend from his army days is coming over for a visit. Dad will really enjoy that I hope today doesn't tire him out too much.

Can't believe what happened in Boston. Such a shock. Of course my dad has a conspiracy theory already. He blames the President saying Obama is doing everything in his power to split the nation.
